    Areas affected...portions of central Nebraska

    Concerning...Severe potential...Watch likely=20

    Valid 092216Z - 092315Z

    Probability of Watch Issuance...80 percent

    SUMMARY...A WW will be issued shortly for portions of central
    Nebraska. Hail and damaging winds are likely initially but the
    tornado threat is expected to increase into the evening. A WW will
    be issued by 23z

    DISCUSSION...As of 22 UTC, visible and radar imagery showed
    convection intensifying over the western NE Panhandle. The
    environment downstream has recovered quickly in the wake of earlier
    clouds while maintaining robust surface moisture with dewpoints in
    the upper 60s, increasing to the low 70s F farther east. A very
    unstable environment (MLCAPE 3000-4000 J/kg) is in place with
    deep-layer shear supportive of organized supercells.

    The ongoing storms should continue to mature with a mixed/cluster
    supercell mode expected to spread eastward. Hail and damaging winds
    are likely with supercells initially where higher cloud bases are
    expected. However, as storms move into the richer moisture, backed
    low-level flow will support a tornado risk. This may increase
    further this evening as a forecast 40+ kt low-level jet expands
    low-level hodographs.
